The hex color #0A488E, also known as Congress Blue, presents some accessibility challenges, particularly in text applications. Its relatively low lightness value (approximately 12%) means that it requires a light-colored text for sufficient contrast. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is needed for normal text and 3:1 for large text to ensure readability for users with visual impairments. When using #0A488E as a background, be sure to choose a foreground text color like white (#FFFFFF) or a very light gray to meet these contrast requirements. Tools like contrast checkers can help verify compliance. Also, avoid using this color for crucial UI elements without careful consideration of its contrast against surrounding colors. If the color is used for links, providing an additional visual cue such as an underline or bolding can further improve accessibility.
